Four things you'll feel in the first 4 - 8 weeks*
Once your body has the form of magnesium it can actually absorb, this is what comes back.
A full night, not in pieces
You go to bed, you stay asleep, and the alarm is what wakes you. Seven - eight hours that actually rest you. Mornings where you open your eyes and feel like you slept.
A quiet mind at night
That moment your head hits the pillow and your thoughts just settle. Your nervous system loosens. The day lets go. You drift off the way you used to before any of this started.
Calm legs, calm body
Your legs feel still. The muscles let go. You stretch out in bed and your body actually relaxes into the mattress instead of fighting it. Most people feel this in the first week.
Energy that's actually yours
You wake up rested and the day has fuel. The 2pm window stays open. You catch yourself in the mirror and look like the version of yourself you remember.

FAQS
I've already tried magnesium and it didn't do anything. Why would this be different?
I've already tried magnesium and it didn't do anything. Why would this be different?
Because what you tried was almost certainly magnesium oxide — or a "glycinate" that was quietly buffered with oxide. Your body absorbs about 4% of oxide. Bisglycinate absorbs close to 90%. It's the same mineral, but one reaches your cells and one passes through you. If you've been disappointed by magnesium, it's not magnesium that failed. It was the form.
How long before I actually notice something?
How long before I actually notice something?
Most people notice sleep changes in the first 4 weeks — falling asleep faster, fewer wake-ups, leg cramps easing. The deeper stuff — the 3am wake-ups stopping, stress feeling calmer — usually kicks in between week 8 and week 12. Give it 90 nights. If nothing changed, we'll refund you.
Will this make me groggy in the morning?
Will this make me groggy in the morning?
No. Magnesium isn't a sedative — it's a nutrient your nervous system needs to produce calm. You won't feel drugged. You won't have a hangover. Most people say mornings actually feel clearer, not foggier, once they've been on it a week or two.
